the invention provides a six-axis welding manipulator which is composed of a base 1, a first arm 2, a second arm 3, a third arm 4, a fourth arm 5, a fifth arm 6 and a sixth arm 7, so that accurate control over a welding gun can be better realized, and welding work with higher difficulty can be realized.

Second embodiment:

based on the six-axis welding robot provided in the first embodiment of the present application, a second embodiment of the present application proposes another six-axis welding robot. The second embodiment is merely a preferred way of the first embodiment, and the implementation of the second embodiment does not affect the implementation of the first embodiment alone.

The second embodiment of the present invention will be further described with reference to the drawings and the following description.

Please refer to fig. 2 and fig. 3 in combination, the six-axis welding manipulator further includes a moving seat 8 fixedly installed at the bottom of the base 1, a plurality of universal wheels 9 distributed in a rectangular shape are symmetrically and fixedly installed at the bottom of the moving seat 8, a plurality of support sleeves 10 distributed in a rectangular shape are rotatably installed on the moving seat 8, a screw 11 is installed in the support sleeves 10 through internal threads, the bottom end of the screw 11 extends to the lower side of the moving seat 8 and is provided with a support cushion block 12, a limit block 13 is fixedly installed at the top end of the screw 11, and the limit block 13 is matched with the support sleeves 10.

A plurality of mounting holes which are distributed in a rectangular shape are formed in the top of the movable seat 8, and the bottom of the support sleeve 10 extends into the corresponding mounting holes and is rotatably connected with the inner walls of the corresponding mounting holes.

The outer side of the support sleeve 10 is fixedly sleeved with a bearing, and the outer ring of the bearing is fixedly connected with the inner wall of the mounting hole.
